摘　　要：基于参数优化设计了一种可处理各类脉冲轨道优化的一般方法,并给出了两种确定最优脉冲数的方法。以脉冲矢量与脉冲施加时刻为未知参数,将脉冲轨道优化设计转为非线性参数优化,用合适的非线性规划算法求解。主矢量理论对所得解最优性的验证表明该方法可行。A new method which would deal with general impulsive orbit maneuver was given out based on parameters optimization design in this paper. Two simple and effective methods were raised to determine the numbers of the optimal impulses. The impulsive orbit maneuver problem was converted to parameters optimization when the velocity impulse vectors and the instant times at which these impulses were applied were chosen as unknown parameters to be optimized. The optimal solutions were calculated by suitable nonlinear program. The optimality of solutions verified by using the primer vector theory showed that this method was feasible.
